Interesting theory. I'd like to add that the higher success rate that occurs when you focus on one point may not be connected to weirdness.

People have limited headspace and attention spans. Whether your ideas are "weird" or not, if you try to push too many, you lower the success rate of all of them.

That's why many brands / marketers choose one or two key characteristics or selling points. More, and the brand is diluted / the audience gets confused.
